Airpods bug switches back and forth from look to iPhone.

Not sure if this is the right thread to post this, but I've just experienced something wrong where I listen to songs on my watch, so I switch to the iPhone and airpods work and stop playing audio. Idk if there is an error with Watch (Series 4), iPhone (X) or My Airpods. The only thing that solved it to me was a network reset that was a problem.
